tdling the block and having the ends of ,the arbor passed therethrOiFg-h and in electrical contact therewith, whi e apairof contact springer supplementthe electrical connection between the arbdr and standard. Electrical connection between the bracket 9' and the contact ,strip p is effected by an arm t which constitutes a port-ion of the means for operating the block andlreversing it to cause it to present its contact and insulating sides -alternately totthe said arm t.

between the-block, andlthe arm flattened as at 2"and;setitransversely to the block, and a coiled s ringia encircling the standard has one end 4f-bearingFupOn one edge of the flattenediportionlof the arbor 'and its opposite :end' engaging-a pinicarried by the disk,

. Theconiiection between the pull chain in-' dicated at 10 and-the frame I: m is eiiected by means ofa segmental plate 12 of insu- "ilating': material centrally perforated to fit overv the standard and fastened to the arm .m'by-an extension 15 from lsuch arm bent around one ed e ofthe plate, which has the lower end-of tiie arbor n projecting through it and coacting with the standard and extension 15 in reventing displacementof the plate with re at-io'n to the arm m. An an-v gular plate with a key hole slot 21 therein is carried by the'under side ofthe plate 12 and accommodated in a recess 22 in the base Inorder to cause the block to coact with v the arm t. th e,u1"born'has the portion-thereof the e ndballor-head of the chain and the wire upon which the beads are strung fitting;

the lined s ell 23; A sto 24 limits the move-. ments' of the flse menta plate and consequently the cont ct block in one direction the en'd'o'f the recess 22 limitsthe movement 1n the opposite direction.

-The threaded shell for receiving the lamp is indicated at 25. l

The. terminal wires 30 and 31 are connected 'to the brackets 9 and. It by the bindbingts crewsi and j. p p

' 'The lelectric' circuit through this mecha 'nis m is from terminal wire 31 through bracketh, lamp shell 25, the "lamp (not shown) screwed, plate a, standard e, arms is andm and springs r, arbor n, lugs g; strip into the k y-hole and being held therein by land-the engagement ofthe 'plate 20 with 1), arm 25, and bracket 9 to the other terminal wire 30. v

The spring 1' together with the arms of the carrier frame afford a sufiiciently good conductor to prevent the flow of enough current through the actuating spring to impart the temper thereof.

. A pull uporithe chain 10 swings the segmental plate-12 and with it the frame m and block 0 until the segmental plate. is stalled by the stop 24, the block 0 meanwhile sliding along the contact arm 13 and the instant the end of the block clears the end of the arm it is swung to the position shown in Fig. 4 by the action of the spring 3 bearing on the edge of the flattened portion 2 of the arbor. Upon the chain being slackened or released the, sprmg returns the segmel-ital plate to its normal position, the block being engaged at one endby the end of the arm It thus causing the spring 3t0 swing the block upon its arbor so that the reverse side thereof is caused to lie in bearing. relation with such arm; the effect being that the circuit is closed or opened and the lamp eitherli hted or extinguished as required, hat I claim is as follows 1.
